Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of compaction equipment, and particularly relates to a splash-proof structure of a compactor. Background Art
[0002] The compaction test refers to hammering a soil sample to understand the compaction characteristics of the soil. Specifically, different compaction energies are used to hammer soil samples with different water contents, and the corresponding dry densities are measured to obtain the maximum dry density and the optimum water content, providing a basis for the design and construction of the filling project.
[0003] According to the specification requirements, during the test, a disturbed soil sample with a certain water content is layered into the compaction cylinder. After each layer is laid, the hammer of the electric compactor is used to hammer the soil sample according to the specified drop height and number of blows. Finally, the compacted soil sample fills the compaction cylinder, and the test data is finally measured.
[0004] The problems existing in the prior art are as follows: during the compaction test, when the compaction hammer falls, the loose soil sample with a low water content will be splashed out of the compaction cylinder. For some soil samples with a higher water content, the soil samples adhered to the bottom and side of the compaction hammer will fall outside the compaction cylinder during the process of lifting the hammer, resulting in some difficult-to-clean mud stains left on the base of the compactor, causing soil sample loss and affecting the height of the soil sample after hammering. If the lost soil sample is replenished during the test, it may cause hand injuries to the test personnel or interfere with the test process, affecting the final test results.
[0005] Therefore, it is necessary to design a protective structure to prevent the soil sample from splashing out, and it can guide the splashed soil sample back into the compaction cylinder to avoid the deviation of the total test volume caused by the loss of the soil sample splashing out of the compaction cylinder.
[0006] Also, due to the change in the volume of each compaction test, there is a situation where it is necessary to replace the compaction cylinder with a larger capacity and diameter. The splash-proof structure needs to be able to adaptively change to facilitate operations such as replacing the compaction cylinder, pausing the test to add new soil samples, etc., and is convenient for disassembly, installation, and storage. Content of the Utility Model
[0007] In order to solve the above technical deficiencies, the utility model provides a splash-proof structure of a compactor. The technical solution of the utility model: a splash-proof structure of a compactor, including a compactor, a compaction cylinder, and a splash-proof cylinder body. The splash-proof cylinder body includes a plurality of outer arc-shaped sheets and a plurality of inner arc-shaped sheets arranged coaxially. The outer arc-shaped sheets and the inner arc-shaped sheets each include an outer diameter surface and an inner diameter surface. The inner diameter of the outer arc-shaped sheet is the same as the outer diameter of the inner arc-shaped sheet. A trapezoidal rubber slider is fixedly arranged on the inner diameter surface of the outer arc-shaped sheet, and a chute adapted to the contour of the trapezoidal rubber slider is provided on the outer diameter surface of the inner arc-shaped sheet. The plurality of outer arc-shaped sheets and the plurality of arc-shaped sheets are coaxially arranged and surrounded to form a splash-proof cylinder body, and the splash-proof cylinder body covers the mouth of the compaction cylinder.
[0008] With the above technical solution, as shown in the attached drawings of the specification Figure 1 and 5 shown, the anti-splash cylinder body is formed by coaxially enclosing and connecting a number of outer arc-shaped sheet bodies and inner arc-shaped sheet bodies. The trapezoidal rubber slider is inserted into the chute to perform radial limit and axially slidable connection, so that the anti-splash cylinder body of the present application can slide circumferentially relative to the circumference. As shown in the attached drawings of the specification Figure 1 open an opening, so as to observe the situation inside the compaction cylinder and fill the soil sample when the hammering pauses. Second, as shown in Figure 5 of the specification, the sheet body connection structure is convenient for disassembly and storage.
[0009] Third, after the anti-splash cylinder body covers the mouth of the compaction cylinder, due to the smooth solid structure of the sheet body, different from other soft covers, the soil sample splashed on the soft cover will stay due to wrinkles. And the soil sample splashed on the inner diameter surface of the inner and outer arc-shaped sheet bodies will slide down along the solid sheet body and return to the compaction cylinder.
[0010] Therefore, the trapezoidal rubber slider is arranged on the inner diameter surface of the outer arc-shaped sheet body. As shown in the attached drawings of the specification Figure 5 shown, this setting makes the inner wall of the combined anti-splash cylinder body have only vertical convex marks and is basically smooth, which will not affect the sliding of the splashed soil sample.

[0013] With the above technical solution, during the compaction process, one out of every 8 compactions is at the middle position, and then the workbench will move back and forth to adjust the position. Therefore, the magnetic base and the compaction cylinder are detachably and fixedly arranged on the workbench and move synchronously with the workbench.
[0014] Further setting of the present utility model: It further includes a micro vibration motor, which is arranged on the support seat and drives the anti-splash cylinder body to vibrate.
[0015] By adopting the above technical solution, the anti-splash cylinder is supported by an adjustable bracket so that it is independent of the compaction cylinder, the vertical height can be adjusted, the magnetic attraction of the magnetic base can be opened and closed, and the horizontal position can be adjusted.
[0016] A micro-vibration motor is further arranged to drive the anti-splash cylinder to produce a certain slight vibration to shake off the soil sample splashed on the inner wall, and the independent arrangement of the anti-splash cylinder avoids the vibration from being transmitted to the compaction cylinder.
[0017] The utility model is further configured as follows: an annular groove matching the contour of the anti-splash cylinder is disposed on the end face of the compaction cylinder mouth, and the anti-splash cylinder is inserted and upright in the annular groove.
[0018] By adopting the above technical solution, in an embodiment without an adjustable support frame, an annular groove adapted to the contour of the anti-splash cylinder is provided on the end face of the compaction cylinder mouth, so as to engage and support the anti-splash cylinder.
[0019] The utility model is further configured as follows: a brush strip is attached to the inner wall of the anti-splash cylinder, and the brush strip brushes off the soil sample adhering to the hammer of the compaction instrument.
[0020] By adopting the above technical scheme, in a further embodiment, a brush strip can be selectively adhered to the inner wall of the anti-splash cylinder, and the brush extends toward the hammer. The hammer will reciprocate and strike the brush, and the soil sample stuck on the hammer will be brushed off by the brush to avoid being carried out.
[0021] Further configuration of the utility model: a plurality of support columns, a limit support piece sleeved on the support columns, and a nut are fixedly arranged around the compaction cylinder on the workbench; one end of the limit support piece is provided with a connecting hole sleeved with the support column, and the other end extends to the outer circumferential surface of the compaction cylinder and is provided with a groove corresponding to the outer diameter of the compaction cylinder; the nut is threadedly connected to the support column and compacts the limit support piece.
[0022] The above technical solution is adopted, through the detachable structure of the limit support, to adapt to compaction cylinders of different diameters and replace support frames of different radial lengths, as shown in the attached manual. Figure 2 As shown, always hold the compacting cylinder against the hammer to prevent it from shifting during the hammering process.

[0033] Such as Figures 1-6As shown in the figure, a splash-proof structure of a compactor 1 includes the compactor 1, a compaction cylinder 2, and a splash-proof cylinder body 3. The splash-proof cylinder body 3 includes a plurality of outer arc-shaped sheet bodies 31 and a plurality of inner arc-shaped sheet bodies 32 arranged coaxially. The outer arc-shaped sheet bodies 31 and the inner arc-shaped sheet bodies 32 each include an outer diameter surface 311 and an inner diameter surface 312. The inner diameter of the outer arc-shaped sheet body 31 is the same as the outer diameter of the inner arc-shaped sheet body 32. A trapezoidal rubber slider 313 is fixedly arranged on the inner diameter surface 312 of the outer arc-shaped sheet body 31, and a chute 321 adapted to the contour of the trapezoidal rubber slider 313 is provided on the outer diameter surface 311 of the inner arc-shaped sheet body 32. The plurality of outer arc-shaped sheet bodies 31 and the plurality of arc-shaped sheet bodies are coaxially arranged and surrounded to form the splash-proof cylinder body 3, and the splash-proof cylinder body 3 covers the mouth of the compaction cylinder 2.
[0034] As shown in the attached drawings of the specification Figure 1 、 5 As shown, the splash-proof cylinder body 3 is formed by coaxially surrounding and connecting a plurality of outer arc-shaped sheet bodies 31 and inner arc-shaped sheet bodies 32. The trapezoidal rubber slider 313 is inserted into the chute 321 for radial limit and axially slidable connection, so that the splash-proof cylinder body 3 of the present application can slide circumferentially relative to each other.

[0035] Third, after the splash-proof cylinder body 3 covers the mouth of the compaction cylinder 2, because of the smooth solid structure of the sheet body, different from other soft covers, the soil sample splashed on the soft cover will stay due to wrinkles. The soil sample splashed on the inner diameter surface 312 of the inner and outer arc-shaped sheet bodies 31 will slide down along the solid sheet body and return to the compaction cylinder 2.
